Identification of a pre-possible multiple system atrophy phase.
Article in Acta neurologica Scandinavica, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesA pre-possible multiple system atrophy (MSA) phase, that is, the period between symptom onset and satisfying the second consensus diagnostic criteria for possible or probable MSA, may exist. The aim of the study was to identify the pre-possible MSA phase and to pursue the earlier diagnosis of MSA. MATERIALS &
methodsWe reviewed 52 patients with a clinical diagnosis of MSA and 430 patients showing any signs of parkinsonism, sporadic cerebellar ataxia, or autonomic failure with other clinical diagnoses.
resultsThe pre-possible MSA phase was noted in 35 patients with a clinical diagnosis of MSA and 13 patients with other clinical diagnoses. During this phase, 16 patients presented with autonomic features first, while they presented later in 32 patients. Between these patients, there was no significant difference regarding parkinsonian, cerebellar features, levodopa response, or Babinski sign with hyperreflexia. Comparisons by autonomic features or autonomic function tests could not be performed due to the small number of patients. "Atrophy on magnetic resonance imaging of the putamen, middle cerebellar peduncle, pons, or cerebellum" and "new or increased snoring" showed high positive predictive values for MSA.
conclusionA pre-possible MSA phase exists. Improved earlier diagnosis of MSA depends on the sensitivity and positive predictive value of autonomic features or autonomic function tests and on the sensitivity of "atrophy on magnetic resonance imaging of the putamen, middle cerebellar peduncle, pons, or cerebellum" and "new or increased snoring" during the pre-possible MSA phase.
